#  osmarender [-r rulefile] [-t title] <osmfile> [<svgfile>]
#
#  This is a wrapper around the osmarender XSL transformation. If you don't
#  specify a <svgfile> it will use <osmfile> with .svg suffix instead.
#
#  To use this set the environment variable OSMARENDER to the path to your
#  osmarender4 directory. In bash this works like this:
#
#  > export OSMARENDER=~/osm/osmarender4
